“…On anisotropic surfaces, surface mobility was noted first on Au(110) [25]. These studies lacked the systematics necessary for extracting quantitative information employed later and/or the cleanliness of UHV [21,22] necessary for an unequivocal identification of atomic processes.…”

Morphological changes on surfaces have been followed in real time by scanning tunnelling microscopy on the time scale of seconds to days. This "on-site on-time" mode has been employed for the observation of decay, motion, coalescence, and shape fluctuations of islands on the low-indexed faces of Ag, Cu, Pt, and Au. For island changes under well-defined conditions, well-established theories are adapted to identify atomic processes and extract quantitative information on diffusion parameters important for growth and stability of nanostructures, such as energies and prefactors. Extension of the "on-site on-time" approach to atoms, dimers, etc. and to dislocations is outlined.

“…The above results will now be applied to investigate the stability of step patterns on Au(110) and Pt(110) surfaces at room temperature (k B T = 25 meV). At this temperature, the surface diffusion (of Au) is probably high enough to enable equilibration of steps on lengthscales of ≈ 100 Å in less than an hour or so [13]. The parameters, used in the estimates are collected in Table 1.…”

Step patterns on vicinal (2 × 1) reconstructed surfaces of noble metals Au(110) and Pt(110), miscut towards the (100) orientation, are investigated. The free energy of the reconstructed surface with a network of crossing opposite steps is calculated in the strong chirality regime when the steps cannot make overhangs. It is explained why the steps are not perpendicular to the direction of the miscut but form in equilibrium a network of crossing steps which make the surface to look like a fish skin. The network formation is the consequence of competition between the -predominantly elastic -energy loss and entropy gain. It is in agreement with recent scanning-tunnelling-microscopy observations on vicinal Au(110) and Pt(110) surfaces.
